Yeah, can get a trainee / improver card which tbh is what you would expect as you are not yet qualified. That will still get you on site as you will still have done H&S exam to even get that. As soon as you have NVQ3 and AM2 then you can get a ECS gold card graded as "Electrician" grade.
When you tested, were you getting 237v between L-E or L&N at your switch? (BTW, you may not even have a neutral conductor at your switch)
Testing at the fitting would give you best indicator of what is going on and you can then determine whether it is a lost line or lost neutral that is the issue.
You won't necessarily need to have a seperate circuit as the only reason you are using a contactor I assume, is because the switching contacts of your stat are rated less than the connected load you have calculated. You will need a circuit suitable to supply your UFH load plus the negligible...
They probably would require him to carry out individual tests purely to show he can.
However, a global IR value will always be lower than any of the individual circuit values because of the resistances being in parallel. If the global value is an acceptable value then all the individual...
Where exactly was the 200Mohm value recorded on the schedule of tests?
As I read it, it sounds like he is actually refering to final/dist circ insulation resistance tests. These are dead tests which would have be carried out with the main switch isolated anyway and subsequently 200Mohm would...
My uncalibrated MFT (calibration is a waste of money) packed up the other week but I don’t charge my customers enough to cover replacing tools and equipment. It’s fine though, I just short line to earth with a paper clip and wear free covid-19 gloves from the BP garage so I don’t belt myself...
If you already have a programmable room stat then you have 2 time clocks in series presently for CH. You don't need that but ca still utilise it like you have been.
Anyway, any 2 channel WIFI time clock will do but depending on your valve arrangement you may then need one with an NC contact...
DNO will need to be informed for a grid tied system.G83 in this case. Also if using less panels and they are all in same orientation, check max string input voltage on inverter, you may be able to run all the panels in series. More efficient as will get to start up voltage level earlier than two...
All points to one thing.......... lack of testing.
The amount of times you hear this same thing is amazing.
What tests were you going to carry out if it was not getting late??
They only mean extending the earth outsider by the term exporting so I am not worried about the terminology. They could be more specific regarding outbuildings (as with Caravans) but it is really because the impact of a PEN failure is likely to be more severe with some outbuildings dependant on...
It only applies to PME because of the of the potential risk of exposed and extraneous conductive parts rising to mains potential if the PEN conductor suffered a broken earthed neutral and the line conductor stayed intact. This cannot occur on a TN-S or a TT as they have separate conductors.
Anything over 32A for whatever reason will then be covered by the fuse or circuit breaker in place. The potential issue is long duration overload overheating and damaging cable insulation but It's not really such an issue anymore in my experience and certainly nothing like the level it is talked...
A experienced inspector has to be able to apply their discretion when applying codes and also be aware of previous editions of the wiring regulations. Something being "Unsafe" and something that is "Not unsafe but could be made safer" are two different things. An EICR should not be used to up...
Loving this thread! Really laughed out loud when I saw Westward's comment on his video about the stanley, that was awesome ?.
That Kieran cannot be serious, that is just mental!!
The car charger comes under Special installations (722). That's what I was getting at when asking regarding why going for TT. He may be still ok with PME still if nothing is extraneous and also that the charger meets criteria of 722.411.4.1 (iii).
